The Seaside protects a small and representative part of the Nova Scotia coastline. The province’s coastal regions are more densely populated than the interior. Such wildernesses are extremely valuable.

Canada’s national parks are part of a network that seeks to represent all of the natural regions of the country. Kejimkujik is an inland park representing the Atlantic Coast Uplands Natural Region. The Seaside was added to the park in 1988 to represent the coastal features of this natural region.
